BlueNRG-M2 BLE 5 (H23R3)

Stage: Production

Available on backorder


H23R3 is a BlueNRG-M2 BLE 5 module based on STM32F0 MCU and BlueNRG-M2 which is very low power application processor module for Bluetooth® low energy v5.2.

The BlueNRG-M2 is based on the BlueNRG-2 system-on-chip, and the entire Bluetooth low energy stack and protocols are embedded into a module. The BlueNRG-M2 module provides a complete RF platform in a tiny form factor. Radio, embedded antenna and high frequency oscillators are integrated to offer a certified solution to optimize the time-to-market of the final applications.
